Bought a used 52" philips tv curved edges, color not correct, need new tube??? where and how much to buy?? any help in correcting this issue


Use a unit called an electromagnet, and wave it around the TV. Your picture probably had a magnet too close to it.

These sets have weak picture tubes, this may buy you some time. It is not worth changing the tubes in the set. The cost would be more then its worth. Try these adjustments until it completely dies. I have the same set.

I think my picture tube is going out on my Zenith System 3 Tv


Hi, Sorry it took someone so long to get back to you, but nobody likes to give bad news. This tv has a 1.7R tube with 530 resolution and an NTSC tuner which means it is analog and with the new change this month you would need a converter box anyway unless you have cable or satellite. Because of this particular tube and the labor to change it, it would indeed more expensive to replace it than buy a new one. Best of luck to you!

Picture tube doesn't seem to stay in place (standard tv)


A very good chance this tv was dropped or bumped. Sounds like the internal plastic frame is broken and will not support the picture tube. Find someone with tv experience to fix this. I would suggest they use a putty found at an auto parts store. To glue the tube and the frame together. This putty is in a plastic tube. You tear off a piece and fold it several times to activate. It will surely do the job.

No picture on tv


probably you need to replace the picture tube or maybe theres a loosed connection in the high voltage circuit or the video circuit due to the fall. if the picture tube is the problem, you better buy a new tv coz replacing it is not practical and economical. but if it is only loosed connection just bring it to a qualified technician for sure he will not charge you too much for this problem. good luck!

Buzzing Noise and TV picture is yellow


Andy, I'm thinking the buzz is from the deflection coil (yoke) on the neck of the tube or the power supply. Probably not the high voltage as you can hear the "buzz". If it's really that annoying, you can take a length of rubber tubing (no metal) and listen to the buzz coming from the chassis kind of like a stethoscope. STAY AWAY FROM THE HIGH VOLTAGE, please. The yellow picture sounds like a blue chroma failure. A tube can be rejuvinated if need be but that's a job for a pro. Hope this helps.
